TECHNICAL FIELD

The present invention relates to a method of creating a work plan forconstruction machinery. More particularly, the present invention relatesto a method of creating a work plan for an excavator.

BACKGROUND ART

In general, construction machinery may perform work according to a workplan. Accordingly, the work plan may have to be accurately transmittedto an operator of the construction machinery or automatic constructionmachinery, such that the construction machinery or the automaticconstruction machinery can perform a correct work according to the setwork plan.

In related arts, in order to transmit the work plan to the operator ofthe construction machinery, a site administrator may deliver a paperprinted drawing, mark a work area directly on a work site surface, orverbally explain. However, in this way, errors may occur during thetransmission of the work plan, and it may take a lot of time to transmitthe work plan depending on a size of a site. Therefore, there may be adifference in a work quality and speed of the site depending on a skilllevel of the operator of the construction machinery.

Even when only a target drawing is transmitted and the work plan isestablished by the operator of the construction machinery, the workquality and speed may be inevitably dependent on the skill level of theoperator of construction machinery.
